Introduction

Purpose

The purpose of this Shopping Cart Android Project document is to describe the architecture and system design of the Shopping Cart software described in the Shopping Cart Business Requirements Document. The intended audiences of this document are the Android developers, QA testers, and system owners that will collaboratively develop the system and possibly extend the system in the future. The Shopping Cart software is design to create and managed grocery shopping lists.

Scope

The document describes the design and implementation details of the Shopping Cart software. The major functions of the Shopping Cart software are to create and manage shopping lists/stores. The Shopping Cart software is to be developed for the Android platform using the object oriented design methodology.

1. Shoppers must access the Shopping Cart application from an Android device (Smart Phone, etc.)
2. The Shopping Cart application must be accessed by the shopper to create and manage shopping lists/stores.
3. The Shopping Cart application is a standalone application with no external interfaces.
4. All interfaces are managed by the Android system.
5. The Android system’s local database would be used to store all data saved by the Shopping Cart application

Overview of Document

The Software Design Document is divided into five sections with subsections. The sections in this Software Design Document are:

1. Introduction
2. Use Case Realizations
3. Architectural Design
4. Data Structure Design
